Since I bought my conversion bus, my floorplan has changed quite a bit. I found a 1995 International bookmobile based on a 3800 school bus chassis. The sides and roof are flat, square, and tall, so I have a lot of room to build. These are the plans that I'm currently working from. (All images rendered in Google's SketchUp. Fantastic and free.)

Overhead plan view: The driver and passenger seats are on swivels and they can face each other over a removable table top. I've since decided that I will have another section of tabletop in front of the passenger seat so there won't be any banging of feet under the one between the seats. Also, the two seats are on quick-detach pedestals so I can more easily work on the interior during the conversion or when I need to get at the rear half of the engine through the inside cover.

Passenger side. The bookmobile had two doors on the right side. I'm keeping the front door as-is, but the back door will be eliminated when I cut off the sides for the Jeep "garage." I have planned for two chest freezers with one converted to a refrigerator. I also want to have a removable workbench that mounts over the two chests, but I'm still thinking of a way to make it easy enough to move that I don't have to stop whatever I'm doing to get dinner out of the fridge. I've also planned a duct that will channel cold air from the window air conditioner to the various parts of the vehicle—when I'm sleeping I can open a vent over the bed and when I'm awake I can open vents further forward.

Driver side: The shower stall will be where I keep the porta-potty when I'm not taking a shower since it's really a waste of space for more than 23 hours out of every day. I also have wire shelves on the inside of the shower door, but I will use a plastic shower curtain to keep the water in the stall and the hard door will remain open while the shower is in use. Fresh water storage is under the platform in front of the bed wall and it should hold between 180 and 220 gallons, depending on how high I make the step.

Looking back from the cockpit towards the rear of the vehicle: Some plans that I've seen are open and airy, but I wanted mine to be as efficient as possible, both in terms of use of a small space and thermodynamically; I want to be able to heat it with a candle and cool it with an ice cube, so a lot of windows isn't an option.

What these don't show is the roof deck and access hatch that I just installed. I will have a swing-down ladder attached to the ceiling so I can quickly access the roof deck and whatever additional storage (dry goods, etc) I have up there.

Here is my first attempt at a floorplan based off a 40' front engine school bus. The idea was to maximize floor space, minimize the amount of construction (this design only has three walls and a few cabinets), and make it as green as possible. The 'greening' of this design will require a much higher initial investment to purchase the appliances, but the pay off will be that this skoolie will be able to boondock almost indefinitely.

Where are your wheel wells? Will you have a removable steering wheel? And what did you do with the engine? Ours takes up a lot of space inside. Between the steering wheel & the engine cover, using our drivers seat as a chair is pretty much a fantasy. Is this a dog-nosed bus?

One thing. Is this for fulltiming or weekending? One person or two? The reason I ask is because climbing across another person to get in/out of bed gets really old, really fast when you have to do it day in, day out. Especially if you have the flu and you are the one having to climb over someone to make a semi fast desperate dash for the bathroom. We disliked it so much that we put an island bed in our bus. After 5 years of climbing over, I decided to "fix" that problem. I'm too old to continue doing that.
